Association between psoriasis and cardiometabolic comorbidities in a racially and ethnically diverse low-income primary care population.

Psoriasis is associated with cardiometabolic comorbidities, including obesity, diabetes, hyperlipidaemia and hypertension. Many studies that established these associations originated from primarily White and/or relatively affluent populations. To evaluate whether there is a differential risk for cardiometabolic comorbidities in racial/ethnic minorities, we performed a cross-sectional analysis comparing cardiometabolic comorbidities between those with and without psoriasis in a racially and ethnically diverse population of 56 987 low-income patients, stratified by race/ethnicity, and assessed whether race/ethnicity acts as an effect modifier for cardiometabolic comorbidities. We found that psoriasis was statistically significantly associated with obesity, diabetes, hyperlipidaemia and hypertension. The association of psoriasis with comorbidities did not differ significantly by race/ethnicity; thus, we did not find evidence of effect modification. However, our diverse, low-income population had an extremely high baseline prevalence of cardiometabolic comorbidities compared with previous populations studied. Our results suggest education and intervention regarding modifiable risk factors are particularly important among vulnerable populations.

Guía de práctica clínica para el manejo de la neumonía adquirida en la comunidad / Clinical Practice Guideline for the management of community-acquired pneumonia

Resumen La neumonía sigue siendo una de las principales causas de consulta y de hospitalización a la que, además de su un alto impacto en términos de morbilidad y mortalidad, se suma la actual problemática de resistencia a los antimicrobianos, por lo que establecer directrices que permitan su adecuado diagnóstico y tratamiento es de gran importancia para obtener mejores desenlaces clínicos y promover un uso racional de antibióticos en estos pacientes. La presente guía de práctica clínica (GPC) contiene recomendaciones basadas en la evidencia para el diagnóstico y tratamiento de la neumonía adquirida en la comunidad en adultos, las cuales fueron realizadas mediante el proceso de adaptación de GPC basadas en la evidencia para el contexto colombiano.

Abstract Pneumonia continues to be one of the main causes of consultation and hospitalization to which, besides its high impact on morbidity and mortality, the current problem of antimicrobial resistance is added; thus, establishing guidelines that allow its adequate diagnosis and treatment is of great importance to obtain better clinical outcomes and promote a rational use of antibiotics in these patients. This clinical practice guideline (CPG) contains evidence-based recommendations for the diagnosis and treatment of community-acquired pneumonia in adult population; these recommendations were made by means of the process of adaptation of evidence-based CPGs for the Colombian context.

Process evaluation of a culturally targeted video for Latinas at risk of hereditary breast and ovarian cancer.

This paper presents a process evaluation of a culturally targeted narrative video about hereditary breast and ovarian cancer (HBOC) for Latina women at risk for HBOC. Spanish-speaking Latina women at risk for HBOC participated in a single arm study (n = 40). Participants watched the video developed by the authors and responded to surveys. We used mixed methods to assess theoretical constructs that are hypothesized mediators of narrative interventions (i.e., transportation or engagement, identification with characters, emotions) and implementation outcomes (e.g., acceptability). Descriptive statistics summarized theoretical constructs and implementation outcomes. We conducted Mann-Whitney U tests to assess the differences in theoretical and implementation outcomes between participants who were affected versus. unaffected and participants with different levels of education and health literacy. We used the consensual qualitative research framework to analyze qualitative data. Participants' mean age was 47.1 years (SD = 9.48). Most participants were high school graduates or less (62.5%). Acceptability of the video was extremely high (Md = 10.0, IQR = 0.2, scale 1-10). Most (82.5%) suggested video dissemination be through social media. Participants were highly engaged (Md = 5.7, IQR = 1.5, scale 1-7), strongly identified with the main character (Md = 8.7, IQR = 2.6, scale 1-10), and reported experiencing mostly positive emotions (Md = 9.5, IQR = 2.8, scale 1-10). Participants with low health literacy and affected participants reported a significantly higher identification with the main character (p<.05). Qualitative data reinforced the quantitative findings. Women reported gaining knowledge, correcting misconceptions, and feeling empowered. Our culturally targeted video is highly acceptable and targets mechanisms of behavior change for narrative interventions. The video is easily disseminable and can be used as an education tool for patients including affected and unaffected women and patients with different education and health literacy levels. Future studies should test the impact of the video in enhancing genetic counseling and testing uptake.

Extraction and Study of the Essential Oil of Copal (Dacryodes peruviana), an Amazonian Fruit with the Highest Yield Worldwide.

Essential oils are highly demanded substances worldwide. They can be used without modification due to their different chemical and biological properties or as natural sources of chemical compounds. The limit in the use of these metabolites is their low yield. In the present investigation, the essential oil of fruits from Dacryodes peruviana collected in the Ecuadorian Amazon was extracted and studied. The essential oil was released from the plant matrix and isolated by hydrodistillation. The yields obtained were 4.8 ± 0.2% and 11.3 ± 0.2% for fresh and dried fruits, respectively, one of the highest yields on record to date. Twenty-five chemical compounds were identified by GC/MS and GC/FID techniques. The principal constituent was α-phellandrene, with 50.32 ± 3.32%. The antimicrobial activity of the oil was assayed against five Gram negative bacteria, two Gram positive bacteria and two fungi. The essential oil exerted a moderate activity against Staphylococcus aureus. The repellent activity of the oil was assayed against mosquitoes (Diptera: Culicidae); the samples with 3%, 2% and 1% essential oil were class 4, and the sample with 0.5% showed to be class 3. The essential oil showed a weak antioxidant activity through the DPPH and ABTS methods.

Latinas' knowledge of and experiences with genetic cancer risk assessment: Barriers and facilitators.

Disparities in genetic cancer risk assessment (GCRA) uptake persist between Latinas and Non-Hispanic Whites. This study utilized a mental model approach to interview 20 Latinas (10 affected, 10 unaffected) at increased risk for hereditary breast and ovarian cancer (HBOC). Participants were asked about their knowledge and perceptions of GCRA, HBOC, risk, benefits, motivators, barriers, challenges, and experiences with GCRA. Using the Consensual Qualitative Analysis Framework, two authors independently coded the interviews and applied the final codes upon consensus. Additionally, interviews were coded to identify whether participants spontaneously brought up certain topics without a prompt. Findings identified multiple barriers and facilitators to GCRA uptake in this population, including patient level psychosocial/cultural factors (e.g., limited knowledge, worry about relatives' risk) and healthcare system factors (e.g., receiving no referrals). There were notable differences in awareness and knowledge between affected and unaffected women (e.g., genetic testing awareness), as well as knowledge gaps that were evident in both groups (e.g., age of diagnosis as a risk factor). To reduce disparities in GCRA uptake, interventions should address identified facilitators and barriers. Differences in knowledge and awareness between affected and unaffected women support the development of targeted interventions that address specific knowledge gaps. This study was registered in ClinicalTrials.gov (NCT03075540) by Alejandra Hurtado de Mendoza, Ph.D.

Developing a culturally targeted video to enhance the use of genetic counseling in Latina women at increased risk for hereditary breast and ovarian cancer.

Disparities for genetic cancer risk assessment (GCRA) for hereditary breast and ovarian cancer (HBOC) persist between Latina and non-Hispanic Whites. There are few tested culturally targeted interventions. We developed a culturally targeted video to enhance GCRA uptake in at-risk Latinas. Interviews with healthcare providers (n = 20) and at-risk Latinas (n = 20) were conducted as formative research to inform the development of the video. Findings from the formative research, health behavior conceptual models, and evidence-based risk communication strategies informed the messages for the script. Then, we conducted a focus group with at-risk Latinas (n = 7) to obtain feedback for final refinement of the script. The final video was piloted for acceptability and potential dissemination in a sample of Latino community health workers (CHWs) (n = 31). Providers and at-risk Latinas suggested using simple language and visual aids to facilitate comprehension. Participants in the focus group identified areas for further clarification (e.g., cost). The result was an 18-min video that illustrates "Rosa's" story. Rosa learns about HBOC risk factors and overcomes barriers to attend genetic counseling. CHWs reported high overall satisfaction with the video (M = 9.61, SD = .88, range 1-10). A culturally targeted video has the potential to reach underserved populations with low literacy and English proficiency.

IL-6 is present in beta and alpha cells in human pancreatic islets: Expression is reduced in subjects with type 1 diabetes.

IL-6 is a pro-inflammatory cytokine upregulated in some autoimmune diseases. The role of IL-6 in the development of type 1 diabetes (T1D) is unclear. Clinical studies are investigating whether tocilizumab (anti-IL-6 receptor) can help preserve beta cell function in patients recently diagnosed with T1D. However, in some rodent models and isolated human islets, IL-6 has been found to have a protective role for beta cells by reducing oxidative stress. Hence, we systematically investigated local tissue expression of IL-6 in human pancreas from non-diabetic, auto-antibody positive donors and donors with T1D and T2D. IL-6 was constitutively expressed by beta and alpha cells regardless of the disease state. However, expression of IL-6 was highly reduced in insulin-deficient islets of donors with T1D, and the expression was then mostly restricted to alpha cells. Our findings suggest that the implication of IL-6 in T1D pathogenesis might be more complex than previously assumed.

Culturally Targeted Video Improves Psychosocial Outcomes in Latina Women at Risk of Hereditary Breast and Ovarian Cancer.

Latina women at risk of hereditary breast and ovarian cancer (HBOC) have lower awareness, knowledge, and use of genetic counseling and testing services (GCT) than non-Latina Whites. Few interventions have been developed to reduce these disparities among at-risk Latinas. This pilot study assessed the impact of a culturally targeted narrative video developed by our team. The study included 40 Latina immigrants living in the United States who were at risk of HBOC, including affected and unaffected women. We assessed pre-post differences in psychosocial outcomes. Participants were 47.35 years old on average (SD = 9.48). Most (70%) were unaffected with cancer, had an annual income of $40,000 or less (65%), an education of High School or less (62.5%), and were uninsured (77.5%). The video significantly enhanced knowledge (p < 0.001), positive attitudes (p < 0.05), anticipatory positive emotions (p < 0.05), and intentions to participate in counseling (p < 0.001). Importantly, the video also significantly reduced negative attitudes (p < 0.05), and attitudinal ambivalence (p < 0.001). The culturally targeted video shows preliminary evidence in improving psychosocial outcomes related to GCT uptake in Latinas at risk for HBOC. This intervention is a promising easily-disseminable strategy to address disparities in GCT utilization.

Neuroinfección por Vibrio cholerae no O1/ no O139 secundaria a la derivación ventriculoperitoneal. Reporte de caso / Vibrio cholerae no o1/ no 0139 neuroinfection secondary to ventriculoperitoneal shunt: case report

RESUMEN La infección de la derivación ventriculoperitoneal es una de las complicaciones más frecuentes en este procedimiento. Vibrio cholerae O1 y O139 es una bacteria gram negativa conocida principalmente por ser la responsable del cólera epidémico. No obstante, existen serotipos no O1/ no O139 capaces de causar afecciones extraintestinales, entre ellas se han reportado casos de neuroinfección. Presentamos el caso de una paciente con 9 meses de edad que posterior a la colocación de una derivación ventriculoperitoneal como tratamiento de hidrocefalia obstructiva congénita, presentó un cuadro de neuroinfección y el síndrome de malfunción valvular; se pudo aislar la Vibrio cholerae no O1/ no O139 en el líquido cefalorraquídeo y en la punta del catéter. Es el primer reporte en la literatura en la que se aísla la Vibrio cholerae no O1/ no O139 en líquido cefalorraquídeo secundario a infección de una derivación ventriculoperitoneal.

SUMMARY The infection of the ventriculoperitoneal shunt is one of most frequent complications for this procedure. Vibrio cholera O1 and O139 is a Gram negative bacteria known mainly for being responsible of the epidemic cholera, however, there are serotypes no O1/ no O139 capable of causing extraintestinal conditions, among them neuroinfection cases have been reported. We present the case of a 9 months old patient who after the placement of a ventriculoperitoneal shunt as treatment for connate obstructive hydrocephalus, presents a neuroinfection condition and valve malfunction syndrome, being able to isolate the Vibrio cholerae no O1/ no O139 in the cerebrospinal fluid and the tip of the catheter. It is the first report in the literature in which the Vibrio cholerae no O1/ no O139 is isolated in the cerebrospinal liquid secondary to an infection from a ventriculoperitoneal shunt.

Provider's Perceptions of Barriers and Facilitators for Latinas to Participate in Genetic Cancer Risk Assessment for Hereditary Breast and Ovarian Cancer.

The Comprehensive Cancer Network (NCCN) recommends genetic cancer risk assessment (GCRA) referral to women at high risk of hereditary breast and ovarian cancer. Latinas affected by breast cancer have the second highest prevalence of BRCA1/2 mutations after Ashkenazi Jews. Compared to non-Hispanic Whites, Latinas have lower GCRA uptake. While some studies have identified barriers for GCRA use in this population, few studies have focused on health care providers' perspectives. The purpose of the study was to examine providers' perceptions of barriers and facilitators for at-risk Latina women to participate in GCRA and their experiences providing services to this population. We conducted semi-structured interviews with 20 healthcare providers (e.g., genetic counselors, patient navigators) recruited nationally through snowballing. Interviews were transcribed. Two coders independently coded each interview and then met to reconcile the codes using Consensual Qualitative Research guidelines. Providers identified several facilitators for GCRA uptake (e.g., family, treatment/prevention decisions) and barriers (e.g., cost, referrals, awareness, stigma). Genetic counselors described important aspects to consider when working with at-risk Latina including language barriers, obtaining accurate family histories, family communication, and testing relatives who live outside the US. Findings from this study can inform future interventions to enhance uptake and quality of GCRA in at-risk Latina women to reduce disparities.

Loss of IDO1 Expression From Human Pancreatic ß-Cells Precedes Their Destruction During the Development of Type 1 Diabetes.

Indoleamine 2,3 dioxygenase-1 (IDO1) is a powerful immunoregulatory enzyme that is deficient in patients with type 1 diabetes (T1D). In this study, we present the first systematic evaluation of IDO1 expression and localization in human pancreatic tissue. Although IDO1 was constitutively expressed in ß-cells from donors without diabetes, less IDO1 was expressed in insulin-containing islets from double autoantibody-positive donors and patients with recent-onset T1D, although it was virtually absent in insulin-deficient islets from donors with T1D. Scatter plot analysis suggested that IDO1 decay occurred in individuals with multiple autoantibodies, prior to ß-cell demise. IDO1 impairment might therefore contribute to ß-cell demise and could potentially emerge as a promising therapeutic target.
